Introduction
to Dental Science
ANTH4523-MWF 9:30 - 10:20
Instructor: Jerome C. Rose Old Main 330 phone: 575-5247
Office Hours:
There will always be a list of open appointment times for at least two days each week posted outside of the Anthropology Office at Old Main 330 at least one week ahead. If you need more time than the 15 minute time slot just put your name down for as many time slots as you think that you will need. The most efficient way to contact me is by E-mail because I can read and answer them late in the afternoon or early evening when I have time to sit at my desk: jcrose@uark.edu. Of course you may always see me in class and set up an appointment. If you call, persist until you reach me as there is no voice mail.
Class Purpose:
Dental Science has been designed to provide you, the student, with a fundamental knowledge of the human dentition including: morphology, anatomy, embryology, growth and development, and pathology. For the predental student, this course will provide a general introduction to the courses taken during the first year of dental school. For the Biological Anthropology student, this course provides the information necessary to begin the study of and research on the human dentition.
Course Organization:
The course begins with a study of dental morphology and functional anatomy and then progresses to embryology and growth. The rationale for this sequence is my opinion that growth and development is easier to understand if it is preceded by a firm knowledge of what the teeth will look like at the end. There will be laboratory sessions for looking at teeth held during regular class time.

Course requirements:
There will be four examinations of equal weight, including the
final. Graduate students will be required to do extra readings, write an annotated
bibliography, and master the dental morphology scoring techniques.
Test Make Up Policy:
there are times when an exam must
be missed, this must be requested in writing with documentation before the day
of the exam and arrangements will be made in writing. If an exam is missed and
there is documentation of a legitimate excuse, then a 20 page library research
project will be assigned and the grade on this will be used for the missed examination.
Terms:
Apical---the surfaces of a tooth that face towards the apex of the roots
Buccal---the surface of canines, premolars and molars facing the cheeks
Cervix---the meeting point of the crown and root (the CEJ-cement-enamel junction)
Cingulum---broad bulge girdling the cervical one-third of the crown
Contact area---area of contact between two teeth where the mesial and distal surfaces of adjacent teeth abut
Crest---large ridges descending from the apices of cusps or connecting two cusps
Crown---the part of the tooth that projects into the mouth; coated with enamel
Cusp---pyramidal or cone shaped elevation on the occlusal surface of a tooth with three to four ridges or crests descending from its apex
Cuspid---elevation smaller than a cusp
Cuspule---elevation smaller than a cuspule
Dentine---the tissue that forms the core of the whole tooth
Distal---the surface of all teeth that faces along the dental arcade away from the median sagittal plane
Enamel---the hard coating covering the crown of the tooth
Fissure---a fault resulting from the imperfect joining of two cusps or lobes
Fossa---round depression
Groove---linear, trough-like depression between cusps
Incisal---the cutting edge of incisors and canines (equivalent to occlusal in the teeth that overlap during normal occlusion
Labial---the surfaces of incisors facing the lips
Lingual---the surface of all teeth that faces the tongue
Lobe---large, rounded projections on occlusal surface
Mammelons---rounded prominence (on incisal margins when they first erupt)
Mesial---the surface of all teeth that faces along the dental arcade towards the median sagittal plane
Occlusal---the surface of all teeth that parallels the plane in which upper and lower dentitions meet. In particular, it is used to describe the surface of premolars and molars that meets in normal occlusion
Pit---small circular, tightly defined depression on crown
Pulp---the living tissue of the tooth
Ridge---similar to crests, but smaller and less sharply defined
Root---the part of the tooth embedded in the jaws; coated with cement
Tubercle---small, rounded prominence on surface of tooth
Wear facet---flat, polished surface created by habitual contact between teeth
